Simple, Light, Kid-Friendly Meals for a Relaxing Vacation?

Q: My family and I (husband and two small daughters) are staying at a lake house for a week in late May, and we'll be cooking for ourselves. Although I love to cook, I'd like to keep things simple so that we can all have a relaxing vacation.

What are your top suggestions for simple, light, lovely, kid-friendly meals? The kitchen is nicely appointed, and I think there is a grill too.
